  • Title: Direct comparison of conventional and computed radiography with a dual-image recording technique.
    Author: MacMahon H, Sanada S, Doi K, Giger M, Xu XW, Yin FF, Montner SM, Carlin M.
    Journal: Radiographics; 1991 Mar; 11(2):259-68. PubMed ID: 2028063.
    Abstract:
    To compare the image quality of computed radiographic (CR) with conventional screen-film images, the authors used a dual-image recording technique. Images were simultaneously acquired with a conventional screen-film combination and a storage-phosphor imaging plate loaded into a single cassette. Wiener spectra and modulation transfer function were compared for both image types. A preliminary observer performance test was conducted with chest images obtained with the dual-image recording technique on portable and fixed equipment. Analysis of physical parameters and observer test results suggests that the conventional screen-film system can provide slightly superior image quality, although the CR system has some advantage in bedside applications.
